I’m going to check the IPC later on today. I have the asbuilt from the ACM donor (2020 Fusion) but not the APIM donor, so I can compare that as well as the info you’ve given me.
As for the antenna, I did double check the mount type and that was correct for roof mount (in that screenshot it may have been different as I was trying to see if that would help but it is back to Roof)
This issue started when the ACM was swapped, yes. If I put the old ACM back in before I did the APIM swap and wiring, the GPS would work. Needless to say, especially without any codes I’m really not wanting to pull the dash yet again.
Did they change the GPS antenna type when they went from Sirius to XM? My car had GPS on the old APIM from the factory but the old one wasn’t X40 compatible.
Since I’m not there, I have to ask:
Did you connect the GPS antenna for the APIM? Was the open circuit corrected?
Did you use the roof mounted antenna or an aftermarket one?
Did the old APIM have NAV?
When you go to the test menu on the APIM, can you see satellites and read signal strength?
For the IPC issues:
In the IPC, check the asbuilt for the ENSS settings.
The first time I did not have it in all the way and it was throwing a code for open circuit. As of right now, the GPS antenna is connected. The old APIM did have Nav and it was functioning.
Bezel diagnostics show no fix and nothing on the signal status pages.
I’ll have to try those sync settings this weekend; I did try some differences from the IPC asbuilt in the donor car but all I got was features that I don’t have showing up.
On that note about downgrading, I’m confused if I can do a reformat or not… I’ve seen people say not to on these newer APIMs but I’ve also seen people say if you did JUST an APIM replacement without changing the screen that it’s safe?
I got a bare APIM so I’m still using the screen that came with my car. I’d like to try everything before throwing more parts at it.
Oops, sorry, wrong post. That does not apply to you. I was doing too many things at once, thinking you had a 2020 unit. You are fine to reformat or downgrade.
Downgrading to Sync 3.3.19052 might make the GPS work. If it does, then the antenna and wiring are good. If that works try installing 3.4.21265.
Alright, I’ll give that a shot. The APIM was manufactured 2019, if that matters, and I don’t want to kill it after all the head smashing I’ve done so far getting it to the mostly working state it’s in now .
Should I try the gyro AsBuilt changes suggested in the other thread as well?
The ENSS settings were set to what was expected (everything but DAB), I set them all to disabled, tried turning on just FM then just Sirius, with the result being the ones that were turned off showing Audio Off when I was listening to that source, and the ones that were turned on still showing as above.
I’m going to try a reformat next for the GPS issue, since that shouldn’t brick my unit and see. It was so bizarre, because when I was doing the initial testing (before I realized you needed the two extra connectors and a newer APIM) popping the old ACM back in would bring it back to life.
Did the reformat and still no luck. No song data in the IPC on FM and SiriusXM, and no GPS. I’m tempted to pop the old stuff back in just to see if GPS works to prove out the old antenna. I can have it done in less than an hour at this point
So the antenna is different throughout the years yes. The Fusion started using the roof antenna for the GPS in 13 but what signals it received changed in 18+(Sirius 360L). The splitter just splits the Sirius signal with the GPS signal. This split is behind the glovebox and is common throughout the Ford models.
You want to make sure there is voltage on the GPS connection.
You have the ACM and APIM connections correct. right? There is a DC blocker in the splitter. Seems likely this is correct if it works with the old APIM.
Yeah, it shows those just fine. It’s just the radio and Sirius sources. Radio isn’t super annoying because it at least shows the frequency, but Sirius just sits there and says 0
Quick question: in the APIM diagnostics should these things about Gyro Sensor and Wheel Sensor say something? Those don’t sound related to the GPS antenna but they are still blank:
and it was throwing a code for open circuit. As of right now, the GPS antenna is connected. The old APIM did have Nav and it was functioning.
